I was always under the impression that a Throttle Body spacer did about as much good as burning a $100 and sprinkling the ashes on the hood while reciting magical incantations... well apparently I was wrong. Still not gonna buy one though.

will it start with starting fluid? if it does, its not getting fuel.

I have had this happen and it acted like it flooded. would not start with starting fluid either. let it sit with the key off and the accelerator wedged to the floor for an hour and it would start then.

Any fix to this? My dads 3/4ton suburban has been doing the same thing. One day it will start, the next it acts like their is no fuel. Had it towed to the mechanic and it worked fine, they kept it all day and worked fine. We had the fuel pump replaced and it still is doing the same thing again.

It sounds to me like a bad ground wire on that comes off the fuel pump. Mine acted up a couple times I had to re-tap a screw into some metal for the ground wire as the old one was corroded.

Update: He has changed the camshaft sensor and the dizzy and cap. Still nothing......We will check the ohms today on the crankshaft sensor. If not just replace it. I will get an update soon. BTW spark plugs were replaced too.
